Knife and fork cleaner



UNITED sTATEs PATENT oEEicE.

SEWALL BRACKET, OF FALL RIVER, MASSACHUSETTS.

KNIFE AND FORK CLEANER.

Specification forming part of Letters Patent No. 27,773, dated April 10, 1860; Reissued February 5,-

T o all whom it may concern:

Be it known that I, SEWALL BRACKET, of Fall River, in the county of Bristol and Commonwealth of Massachusetts, have invented a new and useful Improvement in Rotary Knife and Fork Cleaning Machines; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, ref erence being had to the annexed drawings, making a part of this specification, in which- Figure l, is a transverse section; Fig. 2, a perspective view; Fig. 3, a longitudinal elevation.

The nature of my invention consists in a combination of revolving` fibrous scouringrollers asrepresented by B, Figs. l, and 2, driven by cog-gear D, Fig. 2, set in motion by the crank H.

The lower part of the machine consists of a box or trough in which the lower rollers run, containing the cleansing material, see A, Fig. 2. The knife to be scoured or cleaned is held horizontally between the two rollers, through the opening Gr, Fig. 2. Connected with one of the upper shafts 6, Fig. l, is Va single polishing wheel of leather or fibrous material, see C, Figs. l, and 2, by which the fork to be scoured or cleaned is placed upon said polishing wheel through the opening L L Fig. 2.

To enable others skilled in the art, to make and use my invention, I proceed to describe its construction and operation.

It consists of a box or trough for the cleansing material in which the lower rollers run, united to a frame to support the rollers as represented by A, Figs. l, 2, and 3. The boX or trough and frame I construct of cast-iron in one piece.

B, Figs. l, and 2, are the four scouring rollers formed of elastic brous material, fastened on shafts o b b o, Fig. l, and 0 0 0 o, Fig. 3. These shafts work in bearings N, N, Fig. 3, and are driven by cog-gear D, Fig. 2, set in motion by the crank H.

.su u The fork cleaner is represented by C, Figs. l, and 2, formed of leather or fibrous elastic material attached to one of the shafts Fig. l, or o, Fig. 3.

The upper and lower rollers are kept together with a proper pressure upon the surface of the knife to be scoured or cleaned by the saddle F, Figs. 3, and 2, confined by the rods I, which pass through the case E, Fig. 3, and kept in their proper place by the springs (Z, Fig. 3. The top of the rods I, are fastened to the saddle F, by nuts a, Figs. 2, and 3. The lower end of the rods I, are fastened by the washers, Z9, Fig. 3, which confines the springs, (Z, in the cases E.

C is the upper end of the enlarged hole in the cases E, for the washers, b, to pass up. to the shoulders at C, and then stop, so as to prevent the saddle F, which is the upper bearing of the upper shafts 0, 0, Fig. 3, from rising far enough for the cogs D Fig. 3, to run out of gear.

By the combination of rollers above described, the knife is more easily held, and better cleaned than when but two rollers are used.

d, Fig. 3 are the spiral springs, on the cases E, by which the saddle F is confined with a proper pressure upon the upper bearings, o, o, by means of the rods I, with the Y' nuts a, and washers b, as before described.

Gr, Figs. l, and 2, is the leather lining to prevent the scouring or cleansing material from escaping from the box or trough.

O, Fig. 2, is a cap or lid covering the top of the machine.

What I claim as my invention and desire to secure by Letters Patent is- The combination and arrangement of the scouring rollers B and C, the gears D, the

saddle F, the rods I, the springs CZ, cases A` and E, all substantially as and for the purposes specified.
